Whenever you need a small plastic part or specially a cockpit you can use the "candle technique" like I am using to make the front glass bubble and the cabin of the P-32:
1) Make or cut the part you need ,in transparent plastic or any plastic card ,from wood
or other material.
2) glue a holder to it
3) take a small candle and heat the plastic to the point where you can "mold" it ( Carefull this can burn you!!!)
4) Press the "mold" into the heated plastic to obtain the part you need..let cool.
5) cut the finished plastic part from the mold, clean it, and glue to your model...........
Hope it helps you... ...see photo on the previous post.
